I haven't watched the whole of the video, only about the first half as I'm a bit busy, but...

There are some simple ideas that incorporate some of what he's saying, but perhaps easier to follow. You may well already know these.

First idea is that no note is more than a semitone away from a 'good' note. If you get too much dissonance, move by a semitone. That's rather the essence of approach notes generally ... a dissonance that resolves quickly to a 'good' note. Ideally on the bass that would perhaps be to the 'right' note, but hey....

It also works fine if one plays the tones or semitones both above and below before hitting the 'right' note. That's the 'enclosure'. For example to arrive at C, you might play D, B, C.

Generally the notes from the chord and the notes a whole tone above those sound good.

If you make a mistake, do it a second time and it'll sound like you meant it. That's perhaps a little less easy for a bass player where the rest of the band are expecting solidity ... oh well, one can't always win.
